Monodisperse Electrophoretic Displays Microcapsules Fabricated by Microfluidics

  • 摘要: 本文基于微流控技术,提出一种制备电泳显示液微胶囊的新方法,解决了传统电泳微胶囊制备方法中颗粒粒径不均匀、影响显示器件的显示性能及其驱动波形设计等问题。实验中使用了两种玻璃汇聚流通道(小型和大型),外相溶液为1.5%明胶阿拉伯胶混合溶液,内相为四氯乙烯溶液。当小型通道和大型通道外相溶液流速与内相溶液体积流速比分别为2:1和10:6时,可以得到液滴平均直径分别为47 m和315 m的均匀的微液珠。同时,该方法可以精确控制微胶囊粒径大小,通过调节内外相流速,可以得到粒径在40 m至375 m范围内的大小均匀的微胶囊。与传统机械搅拌法制备的微液珠(52 18.81 m)相比,微流控法制备的微液珠(450.28 m)粒径分布得到了很大改善。该方法为电泳显示器显示效果的改善提供了可行方法。
